Abstract:
Monoclonal antibodies against a variety of receptors and molecules are currently being introduced in clinical medicine. One of these targets is the interleukin-2 receptor alpha-chain CD25. The humanized monoclonal anti-CD25 antibody daclizumab (Zenapax) has been approved several years ago for the prevention of allotransplant rejection and adult T cell leukemia. Following promising observations in uveitis, daclizumab has been tested in a number of small clinical trials in multiple sclerosis based on the rationale that blocking CD25 would prevent the expansion of autoreactive T lymphocytes. The data from this preliminary clinical exploration as well as findings about the mechanism of action of anti-CD25 treatment are summarized in this study.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Multiple Regression
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

Multiple Voltage Sources
In series, the positive terminal of one battery is connected to the negative terminal of another battery. Hence, the voltage of each battery is added to give the net voltage, which is increased because each battery boosts the electrons that enter it. The same current flows through each battery because they are connected in series.
Batteries are...
